whats the favourite way for more power out of these then?

[freak power]

The list is endless

Turbo

2.0

Throttle bodies

NOS

[chumkila]

... also depends on what power output you want.

[essexrsturbo]

no to the turbo (as my 400brake S1 does that)

i want a reliable 150-160 brake

thanks

[chumkila]

In which case I'd say Throttle Bodies are the way to go. freak power is king in this field.

However it won't be cheap.

If i was going for about 150ish bhp i would get the head and cams done and that way you've replaced old with new which can only be a good thing on an old car

[rst in progress]

there was an article about the rs1800 in performance ford or fast ford recently on tuning it, dont know how use full it is

[clarky82]

it was in fast ford.was quite a good article

If i was you mate I would go as far as you can WITHOUT throttle bodies. eg 2.0 with mild cams, chip, focus central throttle body, de cat, nice manifold etc,= a nice flexible useable and quick 150+bhp

The reason I say this is mainly from my own experience: My own RS1800 had a connaught competition engines 2.1 naturally aspirated zetec in it with 45mm jenvey tb's - a lot of money's worth and put out a genuine 220 bhp at the crank @7000 rpm with 179lb/ft torque@5000.

The car was Really fast and fun to drive, especially when "on cam" but awful when in traffic conditions, (very) noisy drank fuel etc.

I think a real 150 ish BHP from a single production-car throttle body will always be more flexibe, driveable and to be honest, faster in real-world driving conditions where you need more low, mid range power, than say the equivalent 170ish Bhp, say from throttle bodies where you would always be having to operate further up the rev range to be in the power band.

throttle bodies are fine so long as it's not your daily-driver because the noise and (lack of) low-speed manners will drive you mad!

Good luck with whatever route you choose mate, Jim.

I would do

2.0 with a well flowed head, fast road cams, a decent exhaust manifold and system, focus steel head gasket to give it 11:1 C/R, power boost valve ( zetecs with std inlets like these ) and a live map.

im defo not going down 2litre route as thats totally pointless having an rs 1800!

i hand build my black series one thats on front cover of fast ford this month (with the old engine in) and know what it takes to get decent power.

but i only really want a 20brake gain over standard im curtain will not need throttle bodys or turbo.

i like the nos idea

i was thinking this, ported head, high lift cams, increase fuel pressure, higher compression, advanced spark, air filter, exhaust, chip

that should be fine, i had a 1600 punto sportingand got 11bhp from just air filter and exhaustand was rolling roaded, dont sound alot but on a normally aspirated engine and ur only after 20bhp so chip exhaust like u said should be fine i would have thought

I would just use the 1800 too mate if that's all the extra power you want, there really isn't much difference in performance between an rs1800-spec 1.8 and a mondeo 2.0 and the 1.8's rev very well as they are a "square" engine as far as bore and stroke are concerned.

Although who would know from 1st glance that it had a 2 litre anyway? they look identical under the bonnet too so shouldn't upset purists too much.

A 1.8 with some fast road cams (don't go wilder than this), head work, decent compression (11:1 as was suggested b4) , focus central throttle body (or just a 2 litre or rs1800 one if you like...) four branch stainless manifold, no cat, decent management (megasquit's good) and fully mapped. That would more than get the power you want + you won't be forking out for nitrous refills all the time!

[freak power]

Well do what i said but not the 2.0.
